Threat Levels

The threat level for the Uk has recently changed from Severe to Substantial.

We cannot, however be complacent and members of the public should always remain alert to the danger of terrorism and report any suspicious activity to the police on 999 or the anti-terrorist hotline: 0800 789 321.
If your information does not relate to an imminent threat, you can also contact the Security Service via the How You Can Help us page.
